Covid-19 cases and deaths in each country

Results - variable selection

  • Liniar correlation analysis lm(days from dec1 to 100 cases ~ diff. variables)
  • Significant correlations:

Respiratory diseases

Life expectancy

Population % living in urban areas

PCA analysis by population demographics

  • PCA showed a clear association with COVID-19 kinetics
  • Relative COVID-19 deaths were more informative than absolute deaths
  • PC1 comprises 44.6% of variation

PCA and cluster analysis

  • Cluster analysis (n=3) based on population demographics data (middle) and on PCA (right)
  • Cluster analysis does not capture COVID-19 kinetics accurately
